Towards modular binary to gray converter design using LTEx module of quantum-dot cellular automata

Abstract: A modular approach to realize the ultra-fast quantum-dot cellular automata (QCA) generic binary to gray converter is presented in this paper. The novel designs here validated fully exploit the intrinsic repetitive capabilities of the Layered T Exclusive OR (LTEx) module in the QCA domain. An efficient logic formulation of QCA design metrics like O-Cost and delay is proposed for the n-bit QCA binary to gray converter designs. The QCA implementation of n-bit LTEx binary to gray converter is compared with the conventional converters. An attempt has been made to enhance the speed of modular binary to gray converter designs. The proposed 4, 8, 16, 32, 64-bit binary to gray converters need 4.35, 15.88, 15.96, 15.7, 16.68% less O-cost and 11.57, 2.61, 9.32, 12.64, 29.25% less effective area, respectively. Thus the proposed layouts offer the smaller feature size, reduced circuit complexity exploiting the modular based design approach. The simulation results have been carried out in the renowned computer aided design tool, namely QCADesigner 2.0.3 with gallium arsenide heterostructure based parameter environment.

Towards a Collaborative Disaster Management Service Framework using Mobile and Web Applications: A Survey and Future Scope

Abstract: Getting the right information at the right time and place is the key for efficient disaster management. Various mobile and web applications are now being used for collecting situational information in digital form, assessing damage, coordinating relief operations and offering different location based services to the affected communities during disaster management. This article provides a thorough investigation on popular web-based and mobile applications currently being used in different countries. Subsequently, the taxonomy of essential services needed for systematic and coordinated disaster management is formulated based on literature review and the authors' interaction with different stakeholders. An outline of a collaborative disaster management service framework is then proposed with the facility of interaction for the stakeholders through their mobile phones to avail the services in different phases of a disaster. A basic version of this framework is implemented to evaluate its effectiveness as a provider of significant actionable information to offer responsive services

Implementation of optimized high performance 4×4 multiplier using ancient Vedic sutra in 45 nm technology

Abstract: With the enrichment of new technology in the fields of VLSI design and communication there is also a demand of high speed and low area. The aim of this paper is to design a multiplier circuit based on Vedic sutras. The algorithms based on conventional mathematics can be optimized and simplified by using Vedic sutras. In this paper we have given the design up to Multipliers based on Vedic multiplication sutra “Urdhva-Tiryakbhyam” the design of 2×2, 4×4 has been designed in DSCH2 and all the outputs have been given. The layout of those circuits has been also generated by Microwind. The internal circuit diagram of all the blocks has been explained The noise, power have been calculated by T-Spice-13 in 45nm Technology. The hardware has also been implemented in XILINX and tested in Basys™2 Spartan-3E FPGA Board.

Power analysis attack resistable hardware cryptographical circuit design using reversible logic gate in quantum cellular automata

Abstract: Quantum-dot cellular automata (QCA) technology leads to rapid high-density combinatory low power exploitation to realize the reversible logic circuit in the nanoscale era. Reversible logic is an alternative to overcome excess energy indulgence of irreversible process. This paper illustrates a cost-effective, energy-efficient Universal Reversible Logic Gate in QCA framework which is capable of designing power analysis attack resistable hardware cryptographical circuit. The proposed (URLGs: U1 and U2) has been tested with simulator QCADesigner V2.0.3, outshined the existing pattern relating to the area, gate count, garbage count, and quantum cost. We found 37.5% garbage minimization is achieved compared to NFT, which is utmost minimization of garbage ever reported in QCA literature. Thirteen three variable standard Boolean functions are considered as logic benchmarks to guesstimate the capability and efficiency of proposed URLG in QCA circuit implementation and synthesizing logic gates. In average, our proposed U2 achieved 36.66% improvement in energy dissipation for different kink energy ratios over early reported work.
